MOLD.

Application filed March 4, 1924. Serial No. 686,862.

To all whom it may concern:

Be it known that I, FRANK P. BUNKER, a citizen of the United States, andresident of North Manchester, in the county of Wabash and State ofIndiana, have invented certain new and useful Improvements in Molds, ofwhich the following is a specification.

My invention relates to improvements in collapsible brick molds, and itconsists in the combinations, constructionsand arrangements hereindescribed and-claimed.

More specifically, the'present invention is an improvement over thatdisclosed in Letters Patent of the United States 1,268,676 grantedto meJune 4th, 1918, or an improved brick mold, and contemplates theprovision of a brick mold comprising separable side and end members andpartitions, the side and end members being adapted to be removed frombricks which are formed in the mold to rest upon a pallet without therebeing any necessity of removing the partition from positions between thebricks, whereby the bricks with the partitions therebetween may remainon the pallet until the bricks are cured while the side and .end membersmay be used with other partitions and pallets to form additional bricks.

A further object of the present invention is to provide a collapsiblebrick mold having the side members and the end members thereof providedwith novel cooperative locking elements for releasably holding the sideand end members in assembled position the pallet having means engagingwith themold when the latter is assembled tending to hold the mold incentered position on the pallet without preventing separation of the endmembers of the mold from the side members thereof when desired.

Other objects and advantages will be apparent from the followingdescription, considered in conjunction with the accompanying drawings,in which- Figure 1 is a perspective view showing a mold embodying thepresent invention in position for use on a pallet,

Figure 2 is an elevation of one of the end members,'showing the normallyinner wall of the. latter,

opposite endswith an upper substantially hook-shaped or right angularlocking extension 3. and a lower similar locking extension 4. The billportion of each of the substantially hook-shaped locking extensions 3and 4 extends downwardly vfrom the body of the locking extension. Theinner wall of the bill portion of each of the locking'extensions 3 isinclined upwardly and inwardly from its lower end as indicated at 3*,Likewise, the inner walls of the bill portions of each of the lockingextensions 4 are inclined upwardly and inwardly from its lower end asindicated at 4: The upper locking extensions 3 extend from. the uppercorner portions of eachendmember 1 in the plane ofthe end member .whilethe lower locking extensions 4 extend from the lower corner portionsofthe end member.

The side members 2 are adapted to cooperate with the end members 1 Eachof the side members 2 issubstantially rectangular and is provided ateach of its opposite ends with an upper substantially hook-shaped orright angular locking extension 5 and with a lower similar lockingextension 6. Each of the locking extensions 5 "or 6 has the billportion, thereof extending upward from its juncture with the body of thelocking extension. The inner wall of each locking ex tension 5 isinclined downwardly and in wardly from its upper end as indicated at endmembers 1 are adapted to engage with the corresponding lockingextensions on the side members 2 so that the side members and the endmembers will be releasably held in position to provide a frame that isrectangular in horizontal sectional contour and hasvertical end and sideWalls. Since the inner walls of the bill portions of co-engag inglocking extensions are inclined as described, the meeting portions ofadjacent side and end members of the frame willbe dra n t ght y again teachother when the cooperative locking extensions of such side d end m mers are engaged w h each t r- The de nd end membe the e will be tightlyconnected together at the corners of the frame and at both the upper andlower ends of the frame.

The inner faces of the end members 1 preferably are smooth while theside members 2 are provided with spaced apart vertical grooves 7 intheir inner faces extending the full height thereof, correspondinggrooves 7 of the two side members being in alignment transversely of theframe and being adapted to engage with the end portions of asubstantially rectangular partition 8 which is slidable vertically inthe frame.

Each of the end members 1' is provided with a horizontal lug or strip 9on the outer face of theend member, the lug or strip 9.

being adapted to serve as a handle or hand holdl a r A pallet for usewith the frame is indi cated at 10 and has a flat upper face,preferably, although not necessarily, comprising an upper face plate ofsuitable metal, such as sheet iron, secured upon a wooden base.

An elongated stop or bumper-.11 is secured on the pallet lOin proximityto one longitudinal edge of the latter and in parallel relation to. suchlongitudinal edge. .A similar stop or bumper 12 is secured upon thepallet 10 in proximity to one transverse edge of the pallet and inspaced parallel relation to said transverse edge. The arrangement issuch that the frame will be disposed substantially in centered relationon the pallet when the frame is placed on the pallet with one of the endmembers thereof against the stop 12 and one of the side members thereofagainst the stop 11.

From the foregoing description of the various parts of the'device, theoperation thereof may be readily understood. "The interior of the moldcomprising the frame resting upon the pallet in the manner described isdivided by the partitions 8 into. a plurality of compartments, each openat its upper end and into which brick forming material may be placed toform bricks of a desired size. While in practice, the spacing betweenthe side walls of these compartments will be such that the bricks willbe formed fiatwise'therein, it is obvious that pros-'ision may be madefor forming the bricks edgewise simply by spacing the grooves 7 of eachside member 2 apart so that. the height of each of the compartments ofthe mold will be greater than the width thereof. Also, it will bemanifest that the size of the bricks which are to be formed may bevaried by varying the spacing between the grooves 7 of each side memberof the frame and if sordesired, the grooves 7 may be omitted and theinner'faces of the side members 2 formed smooth so that a mold adaptedfor use in forming one large block of any suitable material will beprovided.

After the compartments of the mold have been filled with brick formingmaterial, the handles or hand holds 9 of the end members may be graspedand the end members may be lifted bodily until the cooperative lockingextensions of the end and side members are in such position in respectto each other that the end and side members may be separated simply bymoving such members laterally outward. The molded bricks spaced apart bythe partitions 8 may remain on the pallet 10 "until hardened and curedwhile the side and end members may be used without delay with otherpartitions 8 and other pallets 10 in forming additional bricks.

Obviously, my invention is susceptible of embodiment in forms other thanthat illustrated in the accompanying drawings and I .sion andv a lowerhook-like extension at each of the opposite ends thereof, the billportion of eachhook-like extension depending from its juncture with thebody of the extension, anda pair of substantially rectangular endmembers cooperating with said side mem bers, each end. member having, anupper hook like extension and a lower hook-like extension at each of theopposite ends thereof for engaging with the cb rresponding hook-likeextensions at one end of one of theside members, the bill portion ofeach hook-like extension to an. end member depending from its juncturewith the body of' the hook-dike extension.

'2. In a mold of the character, described, a pair of substantiallyrectangular side members, each having an upper hookike extension and alower hook-like extension at each therefore consider as my own allmodificaof the opposite ends thereof, the bill portion of each hook-likeextension depending from its juncture with the body of the extension,and a pair of substantially rcctangular end members cooperating withsaid side members, each end member having an upper hook-like extensionand a lower hooklike extension at each of the opposite ends thereof forengaging with the corresponding hook-like extensions at one end of oneof the side members, the bill portion of each hook-like extension to anend member depending from its juncture with the body of the hook-likeextension, and the inner Walls of the bill portions of co-engaginghook-like extensions being oppositely in- FRANK P. BUNKER.
